preparation example Construction

[0030] In a specific embodiment, a method for preparing a resin lens with a high-hardness film layer structure comprises the following steps:

[0031] S1: Make the hardening layer: S11: Dip the ultrasonically cleaned resin lens substrate into the hardening liquid aqueous solution of the type IM9060 with a mass percentage of 25-30%, the immersion temperature is 10-20°C, and the immersion is 5-10 seconds Finally, pull out the solution at a speed of 1.0-3.0mm / s, and dry it at 70-90°C for 2-4 hours, then take out the above-mentioned substrate and send it to a drying oven for drying and curing. The curing temperature is 110-130°C. The curing time is 120 to 240 minutes to obtain a resin lens with a hardened layer; preferably, it is immersed in an IM9060 aqueous solution with a mass percentage of 28.4%; the immersion temperature is 15°C, the time is 5 seconds, and the pulling speed is 2.0mm / s. The drying temperature is 75°C and the drying time is 3 hours; the curing temperature is 1...

Abstract

The invention provides a resin lens with a high-hardness film layer structure and a preparation method of the resin lens. The resin lens comprises a resin lens substrate, a hardening layer and an antireflection layer, wherein the substrate, the hardening layer and the antireflection layer are sequentially arranged, the hardening layer is located on the surface of the resin lens substrate, and theantireflection layer is located on the surface of the hardening layer; the antireflection layer at least comprises a hardness enhancement layer, the hardness enhancement layer is made of aluminum-silicon composite oxide and is composed of Al2O3 and SiO2, and the molar fraction of Al2O3 in the material is 75%-95%. By strictly controlling the material composition and the preparation process, the hardness and impact resistance of the resin lens for preparing glasses are greatly improved, and the resin lens has a good application prospect.

Description

technical field [0001] The invention relates to the field of resin lenses, in particular to a resin lens with a high-hardness film structure. Background technique [0002] In recent years, the demand for optical resin lenses in the domestic and foreign glasses markets has been increasing. Compared with glass lenses, resin lenses have the advantages of light weight, good dyeing performance, and easy processing. Medium and high refractive index optical resin lenses are more transparent High efficiency, UV protection, ultra-thin and other unique advantages are favored by users. Generally, in the lens industry, the refractive index is above 1.60 as the high refractive index, the refractive index is 1.56 as the medium refractive index, and the refractive index is below 1.56 as the low refractive index. However, on the one hand, the resin lens material is an organic material with a polymer chain structure inside. The difference in the structure of different refractive index mater...
